SPECIFICATION forming part of v Letters PatentlNo. 605,826, dated June 14, 1898.

' Application tiled October 9, 1897.

To all whom it may concern,.-

' Be it known that I, BERN J ASSEN, a citize of the United States, residing at Newark, in the county of Essex and State of NeWJersey, have invented certain new and useful ImprovementsA in Self- Oiling Axles; and I do hereby declare the followingto bea full, clear,

and exact description of the invention, such vthe oiling operations, to enable the wheel to be lubricated with greater ease and without removing the same from its axle, and tosecure other 'advantages and results, some of which may be referred tohereinafter in connection with the description of the working parts.

- The invention consists in the improved self-oiling axle and in the arrangements and combinations of parts of the same, all substantially as will be hereinafter set forth, and finally embraced in the clauses'of the claim.

Referring to the accompanying drawings, in which like letters of reference indicate corresponding parts in each of the several views, Figure 1 is a sectionalvew of a wheelhub applied to an axle and showing the lubricating devices therein. Fig. 2 is a clip for holding the oil-receptacle upon the axle, and Fig. 3 is a plan of a modification in the construction of the oil-receptacle. Fig. tis a plan of the oil-receptacle preferred, and Fig. 5 is an elevation of acertain washer or sleeve for taking the inward thrust of the wheel. Fig. 6 is a detail of a certain guard or projecting plate.

In said drawings,aindicates the wheel-hub,

. and b'the axle,which parts maybe of any ordi nary construction. Said wheel-hub is provided with a suitable box c, which is made Serial No. 654,647.- (No model.)

.out at its upper part,`as at ol', and at its opposite sides,vas at d" d, it is providedwith f ianges suitably perforated to receive the upwardlyex'tending ends of a clip e, the said clip being suitably provided with nuts f, by means of which the said parts are firmly and securely fastened upon said axle.

' At the forward end or side of the receptacle d the same is provided at a point closely vnear the axle with a spout g, which is provided with a passage g to permit the outflow of the lubricant, said spout extending downf Ward into coincidence with the inward end of aspiral groove h, formed on the periphery of the tapering axle. Said groove extends the whole lor nearly the whole length of the axle and is preferably provided with a wick or fibrous cord, by means of which the oil is fed to the hub by capillary attraction, gravity,

Lthe action ofthe hub in connection with the spiral groove, or. of all of such .iniiuenees jointly.

. The saucer-shaped guard c' at the inner end of thel hub serves as a dust-cap to prevent the entrance of dust to the axle, the said guard being centrally perforated to pass over the end of the axle and having a recess c" to receive the spout or provide a passage therefor. Said guard rests against the shoulder b' of the axle and is on its concave side provided With a slight annular bead orrib z'", which provides a bearing lfor a collar j. Said collarvis also provided with a central perforation for the axle and with a recessj for the spout, Fig. 5. At one side said collar j bears against the annular rib or bearing of the guard and at its periphery its into a cupshaped inner end c ofthe box c, and the said guard i takes the end thrust of said collar j and hub arranged against the same.

The box c at its outward end is somewhat reduced in diameter, being shouldered at c", and on the reduced end is Vfitted the inner socketed end 7; of the nut 7o. Said nut is of peculiar construction, being centrally perforated and threaded, and thus adapted to be secured upon the threaded extremity of the axle. At its inner end it is provided with a hollow cylindrical socket 7V" to receive the small end of the box and form a nice joint therewith more or less impervious to the Huid lubricant. rlhe impermeability is increased by means of a leather washer w, interposed between the shoulder c" and the end of the cylindrical part. The outfiow of fluid from the hub is thus effectually prevented.

I prefer to employ a Cotter-pin Zfor keying the nut upon the axle. The nut 7a is also preferably provided with a recess or chamber Z, adapted to receive superfiuous oil and more particularly an y gritty matter which will work forward. rIhe nut is also provided with a ange 7s" to take the outward end thrust of the wheel.

On the outside of the hub I prefer to provide the same with a casing p of metal, which extends inwardly over the guard t, more or less closely engaging its edges to cooperate therewith in preventing the entrance of dust to the joints. The casing p also extends outwardly beyond the opposite end of the body of the hub and is provided with a cover n, suitably flanged to enter the aperture formed thereby and form a closed chamber for the nut 7o, the. Said cover is held in position by screws o or in any other suitable manner.

In Fig. 3 I have shown a construction in which the guard t' is cast in one integral piece with the oil-receptacle. I prefer ordinarily, however, the separate arrangement for purposes of convenience of manufacture. The oil-receptacle d is provided with a hinged cover and catching means for holding the same closed. The cotton waste or wicking of the spiral groove extends directly through the groove to the passage g' to the storagechamber d.

There more or less solid grease is employed as the lubricant, I provide a threaded cover adapted to be screwed into the correspondingly threaded top of the receptacle and serve 'as a plunger for forcing said grease into the peripheral groove. In this event the wicking or waste may be dispensed with. The wicking ordinarilyis held at the outer end by a screw fr. (Shown in outline in Fig. 1.)

Having thus described the invention, what I claim as new isl. The combination with the tapering axle having a spiral groove terminating at the smaller end of said axle at a chamber or recess Z, a wheel having a box c, a nut having its inner end fitted over said box, and its outer end secured to said axle and interiorly between said ends having said chamber or recess Z', substantially as set forth.

2. The combination with the wheel-hub, the tapering and grooved axle, the box c, having the cup-shaped inner end, the collar .7', iitting said cup-shaped extremity and having the recess j, and the guard t, concaved at the side toward said wheel-hub, of the lubricant-receptacle having the spout extending through said guard and into said collar and conducting the said lubricant into the groove of the axle, substantially as set forth.

3. The combination with the tapering axle having a reduced and threaded end and grooved periphery, of a hub having the box c, with a reduced outer end, a nut 7c, adapted to be keyed to said axle and having a flange k", and at its inner end forming a cylindrical socket receiving the reduced end of the box and interiorly having a recess or chamber in connection with the groove of the axle, and means for supplying said groove with lubricant, substantially as set forth.

In testimony that I claim the foregoing-I have hereunto set my hand this ith day of October, 1897.

BERN JASSEN.
